Specification of Letters Patent.

Application filed Kay .23, 1811. Serial No. 829,024.

To all whom it may concern:

Be it known that I, GUs'rAvn W. Gononnn, a citizen of the United States, residing at Homestead, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Flush-Valves; and I do hereby declare the following to be a full,-clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates-to new and useful improvements in automatic flush valves and the object in view is to produce a simple and eflicient device of this'nature dispensing with the usual float.

My invention comprises various details of construction and combinations and arrangements of arts which will be hereinafter fully described and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawing in which I have shown a vertical sectional view through my improved flushing apparatus.

Reference now being had to the, details of the drawings-by letter, A designates an inlet pipe which is adapted to communicate with any source of supply and one end of said pipe enters the shell A and has its end therein upwardly turned and forming a valve seat. Said shell is provided with an annular'flange A upon its inner face, and G designates a valve which has an annular flange G adapted to seat in the groove formed by the annular flange A when closed. Said valve is centrally apertured as at G? for the reception of the guide pin F which de ends from the top L of the shell. A suitable washer L is interposed between the top 'L and the upper edge of the shell and is held securely in place in any suitable manner.

A chamber B is formed within said shell and is adapted to communicate with the ipe A when the valve G is unseated; A not I leads through an opening in the wall of the shell from the chamber B and communicates with an opening in. the wall of a threaded shell H whichis fitted in an aperture in the top L, the bottom of said shell having a beveled aperture N formed therein.

A valve N, preferably beveled about its circumference to conform to the beveled wall of the aperture N, is normally held seated by means of a s ring P which is mounted a out the stem 2 of. the valve and bears intermediate the collar M upon said stem and the bottom of the shell H. A button N? is formed at the top of the stem N and forms a convenient means whereby the valve may be depressed when it is desired to allow the flushing apparatus to operate.

The operation of the-apparatus will be water being turned on from the source of supply fills the pi A and also the space between the valve and the top L by reason of the water passing through the by-pass formed intermediate the circumference of the guide F and the wall of the opening G The pressure of the water in the chamber above the valve G will serve to hold the latter closed. When it is desired to flush the apparatus, the operator by depressing the bottom N maycause the auxiliary valve N to unseat, aflording a vent for the fluid in the back pressure chamber above the valve G and in consequence the fluid pressure exerted beneath the valve G will force the latter upwardly, driving out the water in said back pressure chamber through the ductor by-pass I. The water from the pipe A will then be allowed to flow freely over the seat of the valve G and down through the chamber B. This free flow of water will continue from the passageway A to B as.

long as the auxiliary valve N is unseated. With the closure of the auxiliary valve N, the water under pressure will begin to collect in the back pressure chamber and the fluid pressure in conjunction with gravity will eventually seat the main valve G.

What I claim to be new is A flushing apparatus comprising a shell with a pipe leading throu h an opening therein, upwardly turned an provided with readily understood and is as follows :-The

an open end, forming a valve seat, the inner wall of the shell having an annular groove, an apertured valve adapted to rest-upon the inner end of said pipe and the marginal edge of one of the walls defining said groove,

said valve provided with a circumferential flange disposed in the groove, a top to said shell provided with a dependin a shell fitted in an aperture in said top and having a valve opening in the bottom thereof, a sprin -pressed valve regul opening, an a-by-pass connecting said shells and controlled by said spring-pressed valve.

guide i passingthrough the aperture o the ve ve,

ating said .In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
